This invention relates to an auxiliary air inlet for use in humidifiers especially adapted foruse in supplying moist air to the fuel charge before the fuel charge enters the combustion chambers of an engine and the important aim of the invention is to provide an attachment which may be easily applied without the exercise of unusual skillan-d without detaching many parts of the motor.

- Other objects and advantages will be apparent during the course of the following description. I V

In the accompanying drawing, Figure 1 is a perspective of the attachment applied.

Figure-2 is a sectional view through the attachment applied.

Figure 3' is 'a vertical transverse sectional view taken on line 3-3 of Figure 2.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates a container for water and one side of the container is as shown in Figure 1 somewhat recessed or curved inwardly to conform to the curvature of the adjacent portion of the motor. This permits the container to-be positioned close to the motor so that the water is heated rior to being drawn into the intake mani old 6 as will be described.

Figures 1 and 2 illustrate that a .gasketlike attaching member 7 is adapted tobe p0- sitioned between the flanges 9 of the manifold and the carbureter and securely held in place by the bolts 10 or other fastening de-' vices. The attaching member 7 is provided with a tapered combined neck and valve casing 11 having separate passages 12 communicating with the interior of the attaching member as shown in Figure 3 and-receiving ball valves 14.

In considering Figure 3 it will be seen that the ball valves are normally unseated and rest upon lower stop pins 15. Therefore when the motor is running at a rapid speed with the throttle well open the suction or vacuum in the intake manifold will not be so great and the ball valves will remain open. On the other hand, when the motor is running slowly as for example when the throttle is slightly open the vacuum in the intake manifold will a sufficient-closure? Thus,i-the sgp -lytrjmoiture willincreasefas the'engine' gain be substantially greater and the valves 14 will bedrawn upwardly intoengagement V jwith the valveseats l6 inthe up'p'erlpQftioirs of the passages 12 whereby to cutofijor 11bstantially reduce the} supply oflinois wait to 'vgid'ed the engine; Upper stop pinsllg5 ale. :p

The valve casing has a branch 20 directly communicating with the container 5 to draw the moistened air from the same. Figure 2 very clearly illustrates that an inlet member 24 is extended through the top of the container and terminates adjacent the bottom of the same so that the air which is drawn through the container will be forced to travel upwardly through the water before it may 1 be drawn into the manifold. The air thus drawn through the water is saturated with moisture and when supplied to the engine by way of the manifold will introduce moisture directly into the cylinders.

In carrying out the invention the inlet i member 24 may be provided with a screen 29 at any suitable place so as to prevent water from splashing out of the container- With reference to the aforegoing descripv tion taken in connection with the accompanying drawing it will be seen that the attachment may be easily connected to the internal combustion engine and more particularly to the fuel supply means therefor without materially altering the engine and without the exercise of unusual skill. The proximity of the container 5 to the crank case and the engine cylinders results in the transfer of a considerable amount of heat to the water so that vaporization is aided.

A humidifying device constructed in accordance with'this invention is substantially automatic in its operation. There are few working parts to get out of order and by reference to Figure 3 it will be-seen that by the employment of the separate valves a more or less constant supply of humidified air is assured at the speeds which call for the supply of such humidified air. Relative to the stop pins 15, it will be seen that besides their limiting function relative to the valves 14 they serve to brace the valve casing 11 transversey e ps er s in t rm e e ae e constituting a reinforcing medium for the casing.

Having thus sq ihed the uiniren iqnvliat is claimed is:
